A WORKING ENGINEER’S DESK REFERENCE
Practical knowledge, within reach.
Formulas, drawing principles and design notes arranged for quick use. This is a living collection: the chapters marked “In preparation” will grow as I add reviewed examples and source references.
01 / WORKING NOTES
Mechanics & design.
Start with the existing calculation and component notes. These pages will be revised and expanded chapter by chapter.
Piping design
Process and hygienic piping, size tables, flow formulas, a velocity calculator and P&ID-to-3D routing.
Open notes ↗Stress calculations
Normal, shear and equivalent stress, including 2D and 3D von Mises examples.
Open notes ↗Strain & deformation
Core strain relations and worked examples.
Open notes ↗Design calculations
Additional mechanical calculation notes and quick references.
Open notes ↗GD&T & tolerances
Geometric tolerancing concepts for clearer drawing and inspection decisions.
Open notes ↗Power & motion
Transmission and motion-system design notes.
Open notes ↗Standard components
Common machine elements and selection considerations.
Open notes ↗02 / NEXT CHAPTERS
What comes next.
The structure is ready; each chapter will be published only when the content and its source are ready.
Sheet metal design
Bend allowances, material choices, manufacturing limits and practical formulas.
Chapter in preparationCATIA V5
Surfacing, assemblies, drawings and design workflows from practical projects.
Chapter in preparationA LIBRARY BUILT OVER TIME
One useful page at a time.
The aim is a concise reference for decisions at the design desk, with enough context to know when a formula or rule applies. It grows through carefully checked entries rather than empty links.
